The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Kennebunk Beach. I gotta be straight with you – this one’s a tough beat. The whole 16-day window is pretty much a desert for surfable waves. The forecast shows a long stretch of nothing worth paddling out for, so don't hold your breath.
Right off the bat, from the start of the period, the energy is just not there. We’re looking at weak, small swells that never really get their act together. The best we can see is a couple of days in the middle of the first week, but even then, the quality is poor. The water is sitting at 66°F, which is a touch warmer than normal for this time of year, which is nice if you’re taking a dip, but not for surfing.
The only real whisper of a pulse comes right at the very end. On the 15th of September, Tuesday morning, we see a bump in the combined wave energy to 129 (moderate energy), with a 3ft swell from the SE. But that’s a short period wind swell at 8 seconds, and the wind is onshore. It’s messy and not clean. That’s as close to a standout as we get, and it’s a weak one. Before that, there’s a big gap of days with nothing. After the 15th, it drops right back off again.
For a sheltered spot like Kennebunk Beach, it’s a pretty normal blank run. The break is fairly consistent, but it’s just not getting the right juice. The optimum swell is from the ENE, and we never get that. Instead, we get a lot of small, short-period SE slop with poor winds. This setup looks more interesting for a kite than a paddle, to be honest.
That’s the long and short of it. Keep your gear waxed for another day.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
